a connection at It with the than 4 7 HJOQOMKBE @arleton K. Steins, Mei-ion, Pa,

asalg'nor to The Pennsylvania Railroad Company, Philadelphia, Pa, a corporation of Pennsylvania Application October 9,1944, Serial No. 557,814 4 a. (GE. 165-73) This invention relates to locomotives. More specifically it has reference to steam locomotives of the type described in U. S. Patent No. 2,338,212, granted to me on January 4, 1944, characterized by having a main section with a boiler in its rear end, fuel and water storagespaces in its front end, and independently-swivelied multl-wheel trucks respectively beneath the .boiler and beneath the front end; and a water-carrying trailer section or tender coupled to said main section.

In connection with locomotives of the kind particularly referred to, I aim to provide the transfer of water from the tender to the storage space in the front end of the main section to compensate for the decrease in weight as the fuel is used up, or from said front end storage space to the tender when the fuel supply is replenished, so that the load may be evenly appropriated between the two separately powered trucks and'the tractive effect of the drivers of said trucks kept uniform.

One way in which the foregoing and other objects and advantages may be readily realized in practice will appear from the following detailed description of the attached drawing, wherein Figs. 1 and 2, taken together show the complete elevation of one side of a veniently embodying the present improvement.

With more specific reference to the drawing, it willbe seen that the illustrated locomotive has a main section l0, whereof the body ll is supported atthe front andrear ends by two counterpart similarly-arranged eight-wheeled driver trucks I2. I Each of these trucks is powered through a line shaft and gear mechanism shown in dotted lines and generally indicated by the numeral It, by a steam turbine I! supported on the frame I of the truck, said frame having a swivel body I I. Associated with each powered truck I! is a smaller fourwheeled pilot truck I'l whereof frame i8 is swivel- -ly connected in turn at I! to the forwardend of the frame iii of said driver truck.

With'this arrangement it is possible for the main section. In of the locomotive to traverse track curves of standard radii notwithstanding theigreat length of its body H.

- the body 24 of which is supported by two indedently'swlveliedsix-wheeled trucks 25. With g in the body of the tender is a tank as for boiler feed water. Space may also be set apart in the steam locomotive con- Longitudinally arranged in the 1 body of the main section it of the locomotive age spaces respectively tender 23 for fuel storage, if desired.

In order to make possible transfer of water from the front end of the main section it of the locomotive to the tender 23, or vice versa, 1 have, in accordance with my invention, provided a conduit system comprising two separate pipe lines 2? and it. As shown, these pipe lines 2?? and 2t extend along the main section it of the locomotive between the tank 22 in said main section and the tank 24 in the tender 2%, the terminals at 27c and 28a being flexible. interposed in the pipe line 21 is a displacing means in the form of an ejector 29 (Fig. 1) which may be steam operated, and which when actuated, serves to transfer water from the forward tank H to the rear tank 26. Similarly disposed in the pipe 28 is a displacing pump 30 (Fig. 2) for transferring water from the tender tank 26 to the tank 2i at the front of a locomotive. Thus a be transferred from the tender to the front end of the main section II of-the locomotive or conversely to compensate for changes in the fuel supply as it is used up or as it is replenished, so that the load weight is equally distributed between the two powered truck's I! of the main section 10 and the tractive effect of the several drivers of these trucks, maintained uniform to the advantage of precluding slippage, particularly at starting of the locomotive. Ordinarily I provide manual means (not shown) in the medially-located crew cab 3| of the locomotive for controlling the operation of the ejector '21 and the pump trailer or tender, it is to be understood that, with-(1 in scope of the appended claims, it may be as' readily adapted to other types of locomotives, for example, single section locomotives in which the boiler is arranged between fore and aft storforfuel and for water, and in which the body is supported at opposite ends by separately powered and independently swivelied trucks in generally the same manner as herein shown. It will also be apparent that my invention may beutilized to advantage in still other types offlocomotives for maintenance of equal weight distribution on the drivers.
